Title: Vibration suppressing controller for motor
Inventor: KAIDA HIDETOSHI
IPC: H02P29/00
Filed: 1993-12-14
Abstract: PURPOSE:To realize the suppression of motor vibration with a simple circuit configuration without using an observer and to save time and trouble for adjustment. CONSTITUTION:A circuit for differentiating and amplifying a driving torque command value tauA*, a circuit for differentiating and amplifying a speed detected value omegaM, and a compensating torque computing element having a constitution of adding and subtracting these computed results and a driving torque detected value tauA and inputting its result to a filter by a transfer function are used in place of an observer. A compensating torque tauS2# which the compensating torque computing element 20 outputs is represented by the equation. tauS2#=G (s).(tauA-s.J# omegaM+K3.s.tauA*). This compensating torque tauS2# is inputted to a first amplifier 8, and a driving torque command value tauA* outputted by a speed regulator 5 and the output of the first amplifier 8 are added by a first adder 19. By giving this added result to a current regulator 6, vibration is suppressed.

Title: Image forming method
Inventor: OBA HIROKI
IPC: G03G21/00
Filed: 1989-12-01
Abstract: PURPOSE:To perform a stable image forming action by setting transfer efficiency in a transfer stage at specified rate or more and eliminating a cleaning stage for cleaning an image carrier. CONSTITUTION:An electrostatic latent image is formed on the endless image carrier 1 and is developed. In an image forming method in which the developed image on the image carrier 1 is transferred on a printing medium, it is found out that remaining toner does not cause an afterimage on the printing medium even though the image carrier 1 is not cleaned by separating a cleaning part, taking a transfer device 4 as a transfer roller 4', and setting the transfer efficiency in the transfer stage >=80% by the use of polyester toner and magnetite carrier for electrostatically charging developer to be positive. Therefore, a remaining toner quantity after transfer is set <=20% with respect to an image toner quantity just after development, that is, the transfer rate is set >=80%, so that the cleaning stage is not necessitated and excellent printing is obtained without afterimage on a printing paper.
